Tectia SSH Performance

Tectia SSH has been developed to meet and exceed the requirements of its corporate customer base. Tectia SSH is the SSH implementation of choice of 4 out of 10 Fortune 500 companies.

Tectia SSH implementations are frequently tested for performance in real-life scenarios to ensure that they meet the requirements of our demanding customers. Below are some figures from our test rounds on file transfers.

Secure File Transfer (FIPS Mode)

Tectia SSH Client/Server 6.4 file transfer test in FIPS mode consists of an SFTP transfer of a 500MB random file. The connection parameters are:

  • Cipher: aes256-cbc
  • Mac: hmac-sha256
  • Key exchange: Diffie-Hellman-group14-sha256
  • Hostkey: ssh-rsa-sha256
HostsUpload (Sec)Mbit/sDownload(Sec)Mbit/s

Solaris146.883.40140.913.55
HP-UX26.3019.0126.3618.97

Deep Directory File Transfer (FIPS Mode)

Tectia SSH Client/Server 6.4 file deep directory file transfer test in FIPS mode consists of an SFTP transfer or a directory structure of 465MB of small files in deep directory structure. The connection parameters are:

  • Cipher: aes256-cbc
  • Mac: hmac-sha256
  • Key exchange: Diffie-Hellman-group14-sha256
  • Hostkey: ssh-rsa-sha256

Solaris10162.463.08140.203.57
HP-UX114.944.3594.615.28

Notes:

  • Tests are performed in a Gb network.
  • Recorded upload/download time is calculated from the average of 10 transfer times.
  • Recorded times include time for authentication and time for transferring files.

File Transfers with Conversions

Tests use a 2GB file to measure differences between:

  • Transparent FTP tunneling
  • FTP to SFTP conversion

Tests are run on both Windows (client on Win XP Pro, server on Win 2003EE), and Linux (client and server both on RHEL).
